When the tsunami's wave peak reaches the shore, the resulting temporary rise in sea level is termed run up. Run up is measured in metres above a reference sea level. A large tsunami may feature multiple waves arriving over a period of hours, with significant time between the wave crests.
684 Hakuhō earthquake, Nankai earthquake. Earthquake. The first recorded tsunami in Japan struck on 29 November 684 AD off the coast of the Kii, Shikoku, and Awaji region. The earthquake, estimated at a magnitude of 8.4, [40] was followed by a large tsunami, but there are no estimates of the number of deaths. [56]
A meteotsunami or meteorological tsunami [1] is a tsunami -like sea wave of meteorological origin. Meteotsunamis are generated when rapid changes in barometric pressure cause the displacement of a body of water. In contrast to impulse-type tsunami sources, a traveling atmospheric disturbance normally interacts with the ocean over a limited ...
The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes . It is about 40,000 km (25,000 mi) long [1] and up to about 500 km (310 mi) wide, [2] and surrounds most of the Pacific Ocean . The Ring of Fire contains between 750 ...
227,898 dead [5] [6] On 26 December 2004, at 07:58:53 local time ( UTC+7 ), a major earthquake with a magnitude of 9.2–9.3 Mw struck with an epicentre off the west coast of northern Sumatra, Indonesia. The undersea megathrust earthquake, known by the scientific community as the Sumatra–Andaman earthquake, [8] [9] was caused by a rupture ...

A megatsunami is a tsunami with an initial wave amplitude measured in many tens or hundreds of metres. A megatsunami is a separate class of event from an ordinary tsunami and is caused by different physical mechanisms. Normal tsunamis result from displacement of the sea floor due to movements in the Earth's crust (plate tectonics).
The tsunami at Ryōri Bay (綾里湾), Ōfunato reached a height of 40.1 metres (132 ft) (run-up elevation). Fishing equipment was scattered on the high cliff above the bay. At Tarō, Iwate, the tsunami reached a height of 37.9 metres (124 ft) up the slope of a mountain some 200 metres (660 ft) away from the coastline.
